Green-end veneer recovery and losses : a detailed study in types and volumes

Creator:: Sheffield, Thomas H.
Abstract:: Previous studies have indicated that the largest loss associated with green veneer production occurs at the green veneer clipper. It has been reported that up to 26 percent of the block volume is lost during clipping. However, because of today's processing sophistication, this value is no longer considered current nor...

Three strategies for tree bucking at the harvest site: consequences for the sawmill

Creator:: Acker, Timothy A.
Abstract:: The timber shortage in the Pacific Northwest is forcing sawmill owners to improve the competitiveness of their harvesting and processing operations. A computer simulation and financial statement analysis were used to compare the processing efficiency and profitability of three bucking strategies: log cost minimization (traditional 40-foot preferred-length logs); hauling length...

Use of alternative costs in determining the economic rotation age of Douglas-fir

Creator:: Dahl, Fredrick Henry
Resource Type:: Masters Thesis

Silvicultural and economic aspects of removal of scattered overmature trees from a well-stocked pole stand in the Sitka sprucewestern hemlock type

Creator:: Williamson, Richard L.
Resource Type:: Masters Thesis

Drying of submerchantable length dimensional lumber

Creator:: Swett, Thomas Michael.
Abstract:: As lumber producers are faced with a diminished and increasingly expensive raw material, the need to maximize resource recovery will increase. Trim-ends (particularly from waned boards) often contain some of the highest quality wood in any given log and lack functionality only in length. This waste, traditionally chipped for pulp,...

Regional employment impacts of timber harvest changes in Oregon

Creator:: Gustafson, Richard Dale
Abstract:: Historically the national market for forest products has greatly influenced the economies of Oregon and its regions because of the high dependence of these economies on the forest products industry. With the possibility of decreased timber production in the area and the high probability of increasing demand for forest products...

Pre-harvest measures to reduce the weight of second-growth Douglas-fir

Creator:: Holt, Harvey Allen
Abstract:: The primary objective of this study is to explore the possibilities of two methods to reduce the weight of small commercial timber prior to logging. The two methods studied are injection of cacodylic acid and sour-felling. Treatments were applied in November, 1965 and May, 1966, with final harvest of the...

Simulation of a helicopter yarding system in old growth forest stands

Creator:: LeDoux, Chris B.
Abstract:: Helicopter yarding systems have become a popular tool in removing timber from steep slopes, sensitive soils, limited access areas, and environmentally sensitive stands. Little is known about the system's dynamics. This study is part of a research project to explore "advanced" logging systems as to their economic efficiency and environmental...

Stream protection and three timber falling techniques : a comparison of costs and benefits

Creator:: McGreer, Dale Jay
Abstract:: The objective of this study was to quantify the amounts of logging residues that are added to mountain stream channels as a result of timber falling - logging procedures, and to evaluate these procedures with respect to both ecologic and economic considerations. Three falling - logging treatments were observed: Conventional...
